cross thread for control handling in C#

mais c'est pas vraiment de poisson d'or.

In order to reduce the efforts of getting latest version of source codes from perforce server and compile it on the machine, I used the p4api .NET library in my program. However, it's a long process; so I have to use another thread to handle this task, and bring out the message sometimes to know current progress. I encountered a problem as the title says -- cross thread control handling. my task is done in a newly created thread; and the message will be printed in a listbox control, which is created by the main thread. To utilize the control in another thread, the delegation mechanism should be used. It's not so complicated. Here's a simple sample from codeproject.
